我正在尝试为我的主题创建一个选项页面，其中在选项页面上有一个下拉列表，显示所有类别名称，选项值作为类别的ID号，以便在下拉列表中它本身显示所有类别名称，但是当您选择类别并在前端回显时，它会回显类别ID。
我现在的代码显示了类别名称列表，但也将名称回显到前端。我试图修改它的ID号，但我没有运气。
总而言之，在选项页面上，它需要在下拉列表中显示类别名称，但在前端它应该回显类别的ID号。
编辑：这是我用来创建选项页面的完整代码 - 这一切都在functions.php中：
<?php
$themename = "TGH 2012";
$shortname = "tgh";
$categories = get_categories('hide_empty=0&orderby=name');
$wp_cats = array();
foreach ($categories as $category_list ) {
$wp_cats[$category_list->cat_id] = $category_list->cat_name;
}
array_unshift($wp_cats, "Choose a category");
global $options;
$options = array (
array( "name" => "Homepage Options",
"type" => "title"),
array( "type" => "open"),
array( "name" => "Pick Categories",
"desc" => "Choose a category from the list to do some interesting stuff.",
"id" => $shortname."_categories",
"type" => "select",
"options" => $wp_cats,
"std" => ""),
array( "type" => "close")
);
function mytheme_add_admin() {
global $themename, $shortname, $options;
if ( $_GET['page'] == basename(__FILE__) ) {
if ( 'save' == $_REQUEST['action'] ) {
foreach ($options as $value) {
update_option( $value['id'], $_REQUEST[ $value['id'] ] ); }
foreach ($options as $value) {
if( isset( $_REQUEST[ $value['id'] ] ) ) { update_option( $value['id'], $_REQUEST[ $value['id'] ] ); } else { delete_option( $value['id'] ); } }
header("Location: themes.php?page=functions.php&saved=true");
die;
} else if( 'reset' == $_REQUEST['action'] ) {
foreach ($options as $value) {
delete_option( $value['id'] ); }
header("Location: themes.php?page=functions.php&reset=true");
die;
}
}
add_theme_page($themename." Options", "".$themename." Options", 'edit_themes', basename(__FILE__), 'mytheme_admin');
}
function mytheme_admin() {
global $themename, $shortname, $options;
if ( $_REQUEST['saved'] ) echo '<div id="message" class="updated fade"><p><strong>'.$themename.' settings saved.</strong></p></div>';
if ( $_REQUEST['reset'] ) echo '<div id="message" class="updated fade"><p><strong>'.$themename.' settings reset.</strong></p></div>';

然后将以下代码放在“header.php”的底部：
<?php global $options;
foreach ($options as $value) {
if (get_settings( $value['id'] ) === FALSE) { $$value['id'] = $value['std']; } else { $$value['id'] = get_settings( $value['id'] ); }
}
?>
然后，这是我用来在前端显示已保存变量的代码：
<?php echo $tgh_categories; ?>

这是真的如此吗？如果是，请将cat_id更改为cat_ID
foreach ($categories as $category_list ) {
$wp_cats[$category_list->cat_id] = $category_list->cat_name;
}
EDIT
之后：
foreach ($categories as $category_list ) {
$wp_cats[$category_list->cat_ID] = $category_list->cat_name;
}
添加：
$wp_ids = array();
foreach ($categories as $category_list ) {
$wp_ids[$category_list->cat_ID] = $category_list->cat_ID;
}
改变这个：
array( "name" => "Pick Categories",
"desc" => "Choose a category from the list to do some interesting stuff.",
"id" => $shortname."_categories",
"type" => "select",
"options" => $wp_cats,
"std" => ""),
对此：
array( "name" => "Pick Categories",
"desc" => "Choose a category from the list to do some interesting stuff.",
"id" => $shortname."_categories",
"cid" => wp_ids,
"type" => "select",
"options" => $wp_cats,
"std" => ""),
同样改变这个：
case 'select':
?>
<tr>
<td width="20%" rowspan="2" valign="middle"><strong><?php echo $value['name']; ?></strong></td>
<td width="80%"><select style="width:240px;" name="<?php echo $value['id']; ?>" id="<?php echo $value['id']; ?>">
<?php foreach ($value['options'] as $option) { ?>
<option<?php if ( get_settings( $value['id'] ) == $option) { echo ' selected="selected"'; } elseif ($option == $value['std']) { echo ' selected="selected"'; } ?>><?php echo $option; ?></option>
<?php } ?>
</select></td>
</tr>
<tr>
<td><small><?php echo $value['desc']; ?></small></td>
</tr>
<tr>
<td colspan="2" style="margin-bottom:5px;border-bottom:1px dotted #000000;"> </td>
</tr>
<tr>
<td colspan="2"> </td>
</tr>
<?php
break;
对此：
case 'select':
?>
<tr>
<td width="20%" rowspan="2" valign="middle"><strong><?php echo $value['name']; ?></strong></td>
<td width="80%"><select style="width:240px;" name="<?php echo $value['id']; ?>" id="<?php echo $value['id']; ?>">
<?php foreach ($value['options'] as $option) { ?>
<option value="<?php echo $value['cid']; ?>" <?php if ( get_settings( $value['id'] ) == $option) { echo ' selected="selected"'; } elseif ($option == $value['std']) { echo ' selected="selected"'; } ?>><?php echo $option; ?></option>
<?php } ?>
</select></td>
</tr>
<tr>
<td><small><?php echo $value['desc']; ?></small></td>
</tr>
<tr>
<td colspan="2" style="margin-bottom:5px;border-bottom:1px dotted #000000;"> </td>
</tr>
<tr>
<td colspan="2"> </td>
</tr>
<?php
break;
EDIT
我的坏，我忘记了$
改变这个：
"cid" => wp_ids,
要：
"cid" => $wp_ids,
NEW EDIT
改变这个：
<tr>
<td width="20%" rowspan="2" valign="middle"><strong><?php echo $value['name']; ?></strong></td>
<td width="80%"><select style="width:240px;" name="<?php echo $value['id']; ?>" id="<?php echo $value['id']; ?>">
<?php foreach ($value['options'] as $option) { ?>
<option value="<?php echo $value['cid']; ?>" <?php if ( get_settings( $value['id'] ) == $option) { echo ' selected="selected"'; } elseif ($option == $value['std']) { echo ' selected="selected"'; } ?>><?php echo $option; ?></option>
<?php } ?>
</select></td>
</tr>
对此：
<tr>
<td width="20%" rowspan="2" valign="middle"><strong><?php echo $value['name']; ?></strong></td>
<td width="80%"><select style="width:240px;" name="<?php echo $value['id']; ?>" id="<?php echo $value['id']; ?>">
<?php
$categories = get_categories('hide_empty=0&orderby=name');
foreach ($categories as $category_list ) {

答案 1 :(得分：1)
您是否考虑过使用Options Framework？
制作管理面板需要花费很多麻烦。作为奖励，有类别下拉列表中内置的功能。
答案 2 :(得分：0)
我一直在寻找相同的东西，并且没有找到实际回答你想要做的事的地方，甚至没有找到这个线程。至少在这里他们很接近，但他们仍然在你提供的问题代码中打破了一些功能。但是，我一直在研究这个问题几个小时，而且通常情况下，你工作的时间越长，解决方案就越简单。
我假设您正在尝试让我们WP_Query选择并显示您在新的选项页面中选择的类别的帖子，就像我一样。我发现如果你使用的是名字，WP_Query不喜欢递归筛选类别，但是如果你使用cat_ID就不会...即使使用get_cat_ID也不会。首先，这是我的Front_ page.php中出现的WP_Query
<?php
$feat1= get_option('twp_feat_cat'); //this is the id of your option in the mega array you setup in functions.php
$args=array('cat' => $feat1,'post_type' => 'post','post_status' => 'publish','posts_per_page' => 2,'caller_get_posts'=> 1);
$my_query = null;
$my_query = new WP_Query($args);
$post_counter = 0; //so I can style last post differently with css
if( $my_query->have_posts() ) {
while ($my_query->have_posts()) : $my_query->the_post(); $post_counter++; ?>
<article id="post-<?php the_ID(); ?>" <?php if ($post_counter == 1) post_class('fourcol first clearfix'); elseif ($post_counter == count( $posts )) post_class('fourcol last clearfix'); else post_class('fourcol clearfix'); ?> role="article">
<header class="article-header">
<h2><a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title_attribute(); ?>"><?php the_title(); ?></a></h2>
</header> <!-- end header section -->
<section class="entry-content clearfix">
<?php $thumb = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'original' );
$url = $thumb['0'];
echo do_shortcode( '[rimg src="' . $url . '"]' );
?>
<?php the_excerpt(); ?>
</section> <!-- end article section -->
<footer class="article-footer">
<p class="tags"><?php //the_tags('<span class="tags-title">' . __('Tags:', 'bonestheme') . '</span> ', ', ', ''); ?></p>
</footer> <!-- end article footer -->
</article>
<?php
endwhile;
}
wp_reset_query(); // Restore global post data stomped by the_post().
?>
此代码段从我的主题选项页面获取cat_ID并将其放入$feat1
您的functions.php所需的唯一两项更改正在改变这一点：
$wp_cats[$category_list->cat_id] = $category_list->cat_name;
到此：
$wp_cats[$category_list->cat_ID] = $category_list->cat_ID;
然后修改您的选择<option>标记：
<option<?php if ( get_settings( $value['id'] ) == $option) { echo ' selected="selected"'; } elseif ($option == $value['std']) { echo ' selected="selected"'; } ?>><?php echo $option; ?></option>
到此：
<option value="<?php echo $option;?>" <?php if (get_settings( $value['id'] ) == $option) { echo 'selected="selected"'; } ?>><?php echo get_cat_name($option); ?></option>
我没有在header.php中添加任何内容以使其正常工作。所以这样做不是使用cat_name，而是使用cat_ID，但是在下拉列表中填写用户友好的cat_name，同时仍然将每个条目与cat_ID相关联，我认为这就是你要找的东西。我很抱歉，如果这很长，很晚，或者不是你想要的，但这是我第一次为网站做贡献，这篇文章让我在寻找解决方案时开始了。< / p>
